12 Surprising Costco Foods You Should Avoid

5 min read

If you’re counting calories or are just concerned about your overall health, you’ll want to avoid the following food items at Costco. Some of the items on this list may surprise you!

12. Bananas


Believe it or not, bananas are one of the worst foods you can buy from Costco. But, wait a minute. Bananas are healthy, right? Right!

So, what’s the problem, then? Well, according to Dr. Amy Lee, Head of Nutrition for Nucific, it isn’t the bananas that are the problem. It’s their size.

“If you actually compare one of these bananas to a normal-sized banana that you would find in a regular supermarket, you will realize it’s almost twice as big,” Lee told Eat This, Not That! And, of course, if it’s twice as big, it has twice as many calories.

11. Protein Bars

Protein bars are often touted as healthy snacks that aid in weight loss efforts. I mean, it makes sense, after all. Protein is essential for building lean muscle and shedding those unwanted pounds. And, while these bars are packed with protein, most at Costco are also packed with sugar.

What’s worse is that some of them don’t even have much protein. Instead, they consist primarily of sugars and oils, with a little bit of protein. Scary, isn’t it? That’s why it pays to read the label before devouring any protein bar carefully.

10. Açai Bowls

Acai Bowl

In 2018, Costco decided to switch out some of its food court’s unhealthy items for healthier options. Enter the açai bowl — a frozen, dessert-like treat filled with berries, granola and banana chips. Sounds healthy, right? Yes, it sounds healthy, but is it actually good for you? Well, according to an article published by Business Insider, the açai bowl is the worst item on Costco’s food court menu.

“There’s nothing worse than an unhealthy food masquerading as a healthy one,” the article reads. “It has 30 grams of sugar, which equals over seven teaspoons. For reference, the American Heart Association recommends that men consume no more than nine teaspoons of sugar a day and that women consume no more than six.”

9. Rotisserie Chicken

Rotisserie Chickens

Because rotisserie chicken isn’t fried, people think it’s super healthy. And, it can be. It just all depends on how you prepare it. Unfortunately, when you purchase food prepared elsewhere, you have no way of controlling its nutritional content.

As a result, you can end up with food that’s high in sodium, among other things. For example, Costco’s rotisserie chickens contain a whopping 460 milligrams of sodium per 3-ounce serving! All of that sodium comes from a special saline solution Costco injects into its chicken to boost the flavor. No wonder these birds are so tasty.

8. Bread

White Bread

It should come as no surprise that white bread isn’t healthy. Many of the important nutrients have been removed, and as a result, white bread products are highly processed, high in calories and have minimal dietary benefit.

This includes white bread products sold at Costco, which, for the most part, are low in fiber. That’s why it’s best to opt for whole-grain bread instead. Costco has an organic whole grain bread product that’s not only delicious; it’s also quite healthy.

7. Pizza

Cheese Pizza

There’s a reason why pizza is referred to as “comfort food.” Most comfort foods are so delicious yet so unhealthy. And Costco’s Kirkland Signature Cheese Pizza is no exception. It’s high in fat and sodium.

And, guess what? That pizza sold at the Costco food court is just as unhealthy, or perhaps even more unhealthy. So brace yourselves for this one. Okay, here we go. Just one slice of pepperoni pizza has a whopping 710 calories!

Unfortunately, most people will never know what they’re consuming because Costco doesn’t publish their nutritional information for food court items online.

However, they offer printouts in person, but of course, you have to ask for them. It’s not like they’re just going around handing them out on their own. And, with all those calories, we can see why.

6. Cookies

Chocolate Chip Cookies

Cookies are delicious. Unfortunately, they aren’t good for you. And Costco’s cookies are full of calories and sugar. But then, there are Costco’s giant cookies, aptly named the Colossal Cookie.

It’s a massive treat that’s large enough to eat over the course of several days. The packaging describes it as a “large, soft and chewy cookie featuring decadent chocolate chunks.” The Colossal Cookie is made with real butter, chocolate and eggs.

Fortunately for those of you who are watching your weight or just concerned about your health in general, the Colossal Cookie might not be available in your area. According to an article published by Delish, a Costco representative said in 2018 that the cookie was only available in some regions.

5. Pre-Made Desserts

Pre Made Desserts

Pure white flour, sugar, butter, stabilizers — those are the ingredients in Costco’s pre-made desserts.

And, check this out: Costco’s Kirkland Signature 12″ Cheesecake has a whopping 11 grams of fat in just ONE slice! And, this sweet treat is enormous, too. It weighs 5 pounds and is large enough to serve 16 people. It costs around $18.

FUN FACT: Costco’s cheesecakes have a bit of a cult following. According to an article published by Insider, Reddit fans say that the Kirkland Signature cheesecake is one of Costco’s best desserts.

4. Pre-Made Pantry Goods

Pre-made pantry goods like Hamburger Helper, canned Chef Boyardee pasta and Kraft Macaroni & Cheese are convenient. They make meal prep a cinch. But, unfortunately, they are also quite unhealthy.

That’s because they tend to be loaded with fat, salt and preservatives. Yes, we know you may be pressed for time, but you’ll fare better if you purchase fresh ingredients and prepare your meals from scratch. Don’t worry; Costco has plenty of fresh food items that are available at affordable prices.

3. Chips


Chips already get a bad rap as is, but Costco’s chips are even worse because of the size of the bag they come in. On second thought, it isn’t so much about the size of the bag as it is about our tendency not to be able to eat just one.

And, that’s true no matter if it’s Lays or some other brand. That being said, there’s nothing wrong with enjoying some chips now and then. Just be careful with that big bag of chips, and make sure to keep your portion sizes reasonable.

2. Chicken Bakes

The infamous chicken bakes you can find at Costo’s food court are sold in the frozen aisle for you to take home. Frozen foods are great for saving time, but there’s nothing good about chicken bakes other than their delicious taste.

Containing over half a day’s worth of sodium and unhealthy fats, chicken bakes are not going to benefit your health in any way. Of course, it is ok to treat yourself and get one at the food court once in a blue moon, but having them stocked up at home is not a great idea.

1. Croissants


Biting into a buttery, flakey croissant is a mouth-watering experience. Some may consider croissants to be irresistible. But that’s exactly why you shouldn’t purchase them in bulk at Costco.

The carb-loaded treat has hardly any nutrients and is certain to take your diet down the wrong path. Fortunately, when you eat clean, you crave unhealthy food way less often. So, soon enough, these croissants won’t even be a thought on your mind.
